"Bars are still locked due Custom regs. 15000' used to be the rule. I guess a bit like the Channel Ferries. It seems very outdated, but it's all empires within HMRC; they are more powerful than Police in the UK (have rights to search without a warrant)"
I'm afraid that your information is incorrect. To start with HMRC is not responsible for airport controls any more - it is the Border Control Agency.
Secondly, Border Control is not interested in none dutiable stores. If Ryanair put their own seals on none dutiable stores boxes it is for their own convenience - nothing to do with Border Control. There can be no excuse for not supplying passengers with water after 5 hours on board delay - [even though the passengers were prepared to pay for the water].
The total lack of customer care beggars belief.
